l COMBINED DADOING AND RELISHING- MACHINE.

f Application filed. May 7,

My invention relates to wood-working machines and its principal objectis to provide a machine for simultaneously cla-doing and relishing bothends ofsash rails or other pieces of wood.

A further object of the invention is to provide a machine of thischaracter which is automatic in operation and will do the workautomatically and accurately. y

It is also an object of the present invention to provide a machine ofthis type which will operate on both ends of the length of wood at thesame time and which is capable of being adjusted to lengths of wood ofvarious dimensions.

`With the preceding and other objects and advantages in mind, theinvention consists of the novel combination of elements, constructionsand arrangement of parts and operations to be hereinafter specificallyreferred to, explicitly claimed and illustrated in the accompanyingdrawing wherein:

Figure 1 is a top plan view of a da-doing and relishing machineconstructed in accordance with my invention,v l f Figure 2 is a sideelevation of the same,

Figure 3 is a perspective of one of the door or window stiles-A afterbeing operated on by the machine,

Figure 4 is an end elevation of the machine, and

Figure 5` is a vertical sectional view taken on line 5-5 of Fig. 2.

ReferringV to the drawings in detail, wherein corresponding charactersof reference denote. like parts throughout the sever al views, thenumeral 5 denotes a supporting table including longitudinally horizontalsills 6 and pairs of supporting legs 7. EX- tending transversely of thebeam 6 at the ends thereof are plates-8 and 9, the plate 9 being rigidlyattached to these sills 6 while the top rails of the frame are tubes 10which are perforated on their top side to receive around toothedsprocket thereby permitting the plate 8 to be adjusted toward and awayfrom the plate 9. Pairs of bearings 11 are mounted on the plates 8 and 9in longitudinal alinement and in which a main drive shaft 12 isjournaled, the latter carrying drive pulleys 13 adapted to be driven bya belt from any desirable source or power, not shown. Journaled in thebearings 11 on the plate 8 and through which the 'shaft 12 passes is arelatively short tubular shaft 13a 1924. Serial N0. 711,728.

having driving connection with the shaft 12 by means ofr a spline 14.Journaled on the plates 8 and 9 are horizontally disposed shafts orstocks 15 carrying rotary bits or relishing tools 16 at their innerends. The opposite ends of these shafts or stocks 15 are provided withpinions 17 which are driven by drive pinions 18 fixed to the shaft 12.Also journaled on the plates 8 and 9 and disposed horizontally at theforward ends thereof are shafts 19 carrying cutter or dadoing heads 20,these shafts 19 being disposed at right angles to the shafts 15. Inorder to drive the da-doing heads 20, drive belts 21 are engaged withthe shafts 19and drive pulleys 22 fixed to the main drive shaft 12.

In order to shift the plate 8 toward and away lfrom the plate 9 thefollowing mechanism is provided: Depending from the plate 8 are bearings23 in which a shaft 24 is journaled, the latter carrying at its endsVsprocket or round toothed gears 25 which engage holes drilled in theupper face of the tubes that also act as ways or supports or sills. Itfollows that upon rotation of the hand wheel 28 the shaft 24 will berotated, thereby causing the sprockets 25 to'traverse the tubular ways10 to shift the plate 8 laterally on the tubular sills.

Journaled in the table 5 and below the sills 6 is a longitudinallyextending shaft 31 carrying disks 32 at the ends thereof and arelatively large pinion 33 adjacent one end thereof. A small shaft 34 isjournaled in the table 5 below the shaft 31 which carries a drive pulley34 driven by the drive belt 35 from the shaft 12. A small drive pinion87 is also fixed tothis shaft 34. Jou'rnaled in the frame 5 and inhorizontal alinement with the shaft 34 is a shaft-38 having pinions 39and 40 fixed thereto; the pinion 40 meshes with the pinion 37 while thepinion 39 'meshes with the pinion S3 lto drive the shaft 31.

Extending transversely of the sills 6 at the ends thereof and projectingoutwardly from the forward side of the table 5 is a pair of guide rails41 upon which channel-shaped slides 42 are mounted for reciprocatorymovement. Fixed to the upper faces of the carriages 42 and extendinglongitudinally across the top of the table 5 is a work carriage 43. Theupper face of the slides-42 are formed with longitudinal grooves whichCil gun

are enlarged at their bases and receive the heads or bolts 45 carried bythe'ends of the work carriage or carrier 43. Nuts 45 are threaded on theupper ends of these bolts which are adapted to be loosenedto permit thebolts to be shifted to any position in the slots to adjust the carriagevor work carrier' 43 relative to the slides 42 to accommodate door orwindow stiles or other' wooden'members of various widths. Eccentricallyconne'cted with the disks are pitinen 46 having operative connectionwith the slides as indicated at 47.

Fixed to the opposite' faces ofthe plates 8 and 9 and disposed betweenthe carriage or work carrier=43 and adapted to support theends of thestiles or other work indicated at' W are angle irons 4S, the latterbeing secured to the plates 8 and 9 by means of slot 4or boltconnections 50 to permit these plates tombe adjusted vertically toaccommodate wood of various thiol-messes.

Fixed to the carriage or worl; carrier 43 at its longitudinalY centerand extending at right angles thereto is an arm 5l which underlies thework and terminates in an upstanding abutment 52 at its inner endadapted to engage the worl to pull the same way from the relishing toolsand cla-doing headsv as the work holder or carriage moves away from thelatter.

The operation of the machine is as follows: The'drive shaft l2 beingdriven from any suitable source rotates the relishing bits and da-doingheads and through the medium of thev gea-ring above mentionedreciprocates the carriage or carrier 43 toward and away from therelishing bits and cla-doing heads. As the' carriage moves toward therelishing bits and da-doing` heads the work resting on the angle' irons48 is moved into engagement with these tools and remains in suchposition long enough for the ends of the wood to be chippedolf orda-doed and at the same time the relishing bits perform the relishing orgrooving of the work. As the carriage or work carrier 43 movesawayfromthc tools thework is engaged by the abutment 52 and moved outwardlyaway from the tools to kpermit the operator to remove the same from themachine and place a new piece of work in position for operation.

It is understood that the form of' my inventionV hereinshownand'described is to be taken as a. preferred example of tlie same,and that variouschanges inshape, size and arrangement ofpa'rts in ay beresorted to without departing from the spiritv of the inventionA or thescope of the subjoined claims.
